Lightswitch Toggle adapter

This is probably pretty niche, but it's an adapter for the pictured marine momentary switch so that I can still attach a faceplate to the switch. Makes for a very satisfying way to trigger automations in home assistant with the relay in detached mode.

I connected all of the left side contacts of the switch to each other and same for the right side so that wether I flip up or down, it acts as a singular momentary switch. If you wanted, you could connect a second relay and have different relays for up or down.

I have the switch connected to the appropriate terminals in a sonoff zigbee relay. This will probably work for other switches as well, but, for the record, the threaded portion on mine has a 12mm diameter. 

In my case, I wired up the switch and relay, put the switch through the adapter and mounted the adapter to the box. After that, I slide the faceplate on and attach as usual. Then, I put on the washer and nut for the switch on it's threads and attached to the exterior of the faceplate.

This is not electrical advice. Anything you do is at your own risk.
